To aZl whom it may concern.-

Be it known that I, J OHN E. ERIoKsoN, a citizen of the United States,residing at St.'Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Journal-Boxes, ofwhich the following is a specification.

My invention relates to boxes or bearings for shafting, and especiallyto shaft-hangers; and its objects are improvement of the constructionwith a view chiefly to obtaining better lubrication of the bearings,while effecting a saving of oil and facilitating the placing andrenewing of the brasses or antifriction metal.

Stated in a general way, my improved devices comprise a pair of separatemetal pieces lined with Babbitt metal or equivalent material placed atopposite sides of a collar on the shaft and held in place within a twopart shell, an oil-chamber in which the collar rotafes, and means forproperly distributing the 01 companying drawings, in which Figure lis atop View of the journal-box and a portion of a shaft. Fig. 2 is a sideor front view of the same. Fig. 3 is a vertical longitudinal section onthe linew w of Fig. 1. Fig! 1 is a plan view, the cover and the upperbrass at the left of the collar having been removed to showth'e'interior construction; and Figs. 5 and 6 are cross-sections on thelines a: w and 2 .2, respectively, of Fig. 4:.

In the drawings, 1 designates a shaft, and 2 a collar secured on theshaft'by set-screws 3. The hanger or shell, which may be suspended orsupported in any convenient way, comprises upper and lower members 4 and5, respectively, secured together by bolts 6, a suitable packing 7 beinginterposed to prevent the leakage of oil at the joint. An oil-chamber 8is provided in the lower portion of the member 5. A lateral hollowextension 9 in communication with the oil-chamber and provided with anupright glass tube 10 enables the level of the oil to be seen fromwithout. Oil can be introduced to the chamber through the tube 10 andduct 9 or through the openings in the shell and bearings hereinafterdescribed. A hole in the bottom of the chamber 8, closed by a screw-plug11, permits the oil to be discharged when desired. Access to theset-screws 3 is had through an opening 12 in the shell members foradjusting the collar on the shaft, and the opening is closed by ascrew-plug 13.

Such devices are illustrated in the ac-' Within the lower half-shell 5,at each side of the collar 2, is a pillow 14 and a cap 15, lined withBabbitt metal 16 or other suitable antifriction material, to provideproper bearings for the shaft. The pillows or bases 14 have lugs 17 attheir sides, which extend into recesses 18 in the walls of the shell 5to prevent the pillows from turning, and they also have projectingannular ribs 19, the outer sides of which are adjacent to correspondingribs 20, formed on the inner walls of the shell to limit outwardmovement. At one end are screws 21, provided with lock-nuts 22 foradjusting the pillow at that end with respect to the position of thecollar 2.

The ribs 19 project above the upper surfaces of the bases 14: intocorresponding sockets formed in the lower edges of the caps, and thelatter are thereby held from lateral movement on the bases. The caps areheld down on the bases by screws 23, inserted from the top of the shell4 and bearing on lateral lugs 24:, formed on the sides of the caps. Onthe inner ends of the pillows and caps are rims 25, having facings26,which are continuations of the brasses 16.

The caps have holes 27 beneath openings 28 in the shell, which arefilled with cotton-waste 29 or like material, and the pockets are closedat the top by screw-plugs 30. Near the collar 2 the caps have oil-holes31 leading to the shaft from depressions or reservoirs 32 in their uppersurfaces. On the top of the collar is placed a strip 33 of felt or otherfabric, which extends across the collar with its ends in the depressions32, for the purpose of wiping the oil from the collar and conducting itinto the reservoirs 32. The strip is held in place by a metal clasp 34:,having downward catches 35, which engage in notches 36 in the rims 25and prevent the wiping device from being carried around by the collarrotations. Narrow channels 37 are out along the inner surfaces of thebrasses from the oil-holes 31 to the holes 27 for the flow of oil alongthe upper surface of the shaft.

The pillows 14 and the brasses 16 they support have suitable openingsthrough which wicks 38 or like devices extend to the under-' lyingoil-chamber 8 for conducting oil by capillary attraction to the undersurface of the shaft.

The two pillowsor bases 14 are alike in construction and areinterchangeable, and the same is true of the two caps 15. When any ofthese parts have become so much worn as Babbitt metal or otherantifriction metal can be readily taken from the removed pillows or capsand renewed for future service. In use the devices have proved verydurable and economical and the lubrication of the bearings has beenentirely satisfactory.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s
